The West Australian Liberal Party's only woman in the state parliament's upper house is set to quit politics.
MLC Donna Faragher on Wednesday said she would not stand for re-election in 2025 after 20 years as the member for East Metropolitan Region in Perth.
The former Barnett government cabinet minister was the youngest Liberal woman to enter the WA parliament when she was elected in 2005 at age 29.
At the end of her term, she will retire as the party's longest-serving female member in either house of the parliament.
"It is an honour and privilege to serve as a member of parliament and to represent the East Metropolitan community in the Legislative Council, a region where I have lived all my life," she said.
